I moved it from my own WordPress. If it was successful, it would be gFW.

Before the start, I wrote a song passionately, which fully expressed my love for the motherland, the country, nature, and the tech-free world.

First, the country's economy was too high, and then the country's policy was superb.
The weather for three hours is not good, and the four hours are really good.

You have to give yourself the most energy to live. When a group of attackers enter the water, they have to force me to remove the real TV from the door.

Yes, it will be impossible to make more money only when some of the "Dynamic Balance" products in the fund market are balanced. If I have more than ten yuan of money in a month, I may as well have to prepare a handful of Sweet likes for my local snacks.

Okay, that's why I'm trying to make it unfeasible (which is cool.

I have read a lot of cases before, but I haven't borrowed anything. In fact, my environment is so special. Living in this difficult human-like CBD, looking at the unclear windows and the unclear AP standards on the screen, I started to suffer from pain points between the two legs.

Main challenges

1. Non-distance. A 30-bit-high hybrid structure was built before, and the two-point architecture was relatively low.

2. dry weight. The entire 2G memory segment is close to-70dbm or above.

3. Daily rack setup is difficult. There are no devices, platforms, and other devices in combination with the location of the device.

Basic Strategy

1. One reflection communication. In fact, this is not a problem. All users who know nothing about communication can do so. As long as you have an ox X and eme God Ma. Of course, I am talking about a reflection using the big picture of the weekly chart. Because my living environment is low, I have been using this method for the past N years for non-telecom communication. I did not say that my best success rate is 200 km/0.35w, right?

2. Non-Standard Indexing rate. There are a lot of things on Taobao, but I think it is more difficult to bring them to North America. Be careful when the FCC bit you down.

3. A user-defined network and special support channels. A user-defined network is easy to install. Special hosts can be easily installed on the windowsill or plane.

Implementation requirements

1. throughput. Every non-domestic network must take an exam. Of course, the sooner the problem is, the better.

2. renewal package. Non-Real-Time Streaming can tolerate a high packet rate. In contrast, Real-Time Streaming cannot tolerate packet loss.

3. Shake motion. Real-time tasks are sensitive to shaking, and vice versa.

Project Implementation

Let's start by setting up the hosts. Since you pay for your money, you must be unable to set up the price. On Taobao, I found two high-power ubnt 150m one-body web pages. The tablet around 14dbi is installed inside, Poe is used for power supply (no other method for power supply), waterproof and plastic. The requirements are basically met. Although they are quite shanzhai, that's the case. Render manager has used Card X + 16dbi Yagi in the early stage, and the email can basically pass through. However, because it was the first time to get this stuff, he did not dare to invest too much money. This is a set of 300 outgoing cell, with the host, bracket, and Poe combination, and I have built my own webpage.

Now that you have a role, it is a problem to maintain security. Because there are no hosts, platforms, and other locations that can be installed, I can only develop my imagination and put my imagination on the camera. This time I used two types of specification, I and L. In fact, they are all used in the Risk Control Project to fix the stand for the injection head of the external bank. taotao has a cheap price of about 15 yuan. However, when the sky is high, the East is very dangerous, so it is best to have a better quality. (Four welding points are required for a cheaper head. Do you have any concerns ?)

(L-type linear regression, linear regression is fixed to linear regression)

(I-type linear regression, linear regression is fixed on the windowsill)

(Of course, I-type linear regression can also be hashed, such as fixed above the window edge. But pay attention to security ......)

The two upstream regions are both 30cm High. The L-type memory is about 8cm away from the memory. There is no limit in the number of bytes, but the rough limit is correct.

With zookeeper, You have to install it.

Warning: high-altitude external operations are highly experienced. If there are no security measures, it may cause serious loss of production and physical damage (or death ). All security items must be secured and fixed, and all construction personnel must take proper high-altitude safety measures.

My security tools include but are not limited to: creating a computer (just pay more than 100 yuan, it is better to close the door) the expansion bolt of the mouth joint, the durable screw screwdriver of the handle (screw knife), the nut, the Niigata belt, and the nut. To avoid damage to your own products during security, you must wear a security helmet, eye mask, anti-noise masks, anti-noise ear plugs, and anti-skid gloves, and wear sports clothes and shoes.

Find the location, use a mirror to pull out the four screw holes in the mirror, and then upload them to the upper-right corner, the deep root of the eye is determined by the expansion bolt. Please try again later. Just tap it. Please refer to the following link for more information.

Then, locate a joint position in the window box, and upload a hole to the window box. Wear a lens and put it on the lens of RJ45 waterproof head, and then fill in the crystal head. It seems that the RJ45 outlet of this website is not very standard. I am a golden wave crystal head that is used in all kinds of places, you have to polish it to get stuck. (Do not wear a lens. If it is not waterproof, it will be a silly task to create a crystal head. Hahaha)

After the basic configurations are completed, you can start to configure the website.

Ubnt is an airview feature, which is a simple analytic component. This analysis can be done on both sides of the web site. Find a very empty keyword and test your guide.

How can I write a word about the power field here. You don't need to talk about 2.4g. They are all the APS in the weekly keyword. 2.3g somehow, the back-to-noise ratio is higher. There are some unknown holding credit points on G. What kind of things may be uncontrolled. On the 2.6g server, an external website (20 mb of 54m) is generated ). In summary, the percentage of empty segments is quite high, but the empty segment of the missing segments is very difficult to find. There are still some other 20 m cases, and the 40 m dry belt will basically not think about it.

We must carefully examine the question of what we want to do. The biggest possible reason for this is to write a package. At these two points, the system runs the kernel in five seconds. When the bandwidth package is too heavy, it will cause the kernel to switch back. At that time, it will bring together a bunch of local hosts on the VPN to re-collect the bandwidth, this is a very worrying question.

Possible bandwidth issues (this is not about untrusted bandwidth, but the bandwidth of the network speed). In fact, it is about signal-to-noise ratio. The higher the signal-to-noise ratio, the higher the band-to-band ratio. However, this time I reflected that the decline was not small, so there would be a signal that is not higher than-75dbm (back noise-around 95dbm ). A 40 M bandwidth (that is, a non-trusted bandwidth) can be used to generate a bandwidth of about 60 Mbps at most. I want to increase the signal-to-noise ratio of 10 dB for a Mbps estimate. It is basically okay, but it is also useful.

The no-bandwidth mode uses the Station WDS/ap wds. It is said that the ubnt firmware can set a higher throughput. The lower the tracking rate of the device, the better. The more hosts, the slower the startup and shutdown. It is best to set the MAC address of the AP. When the bandwidth is GB, it is very difficult to find someone else.

You can use TKIP to encrypt something. Tell you not to use AES, which means the data source may also affect the throughput. TKIP does not look at the RC4 used. It is very difficult to crack things at a time.

Others, the airmax in ubnt is the best. When it turned out, the effect of the single play package was not good, and the layout of the multicast package collapsed. I don't know if it was a firmware bug. Ack selects auto-motivation, so that the website can be adjusted by itself.

Result

1. throughput. The shared bandwidth file on the local area network can be larger than 2 MB per second.

2. renewal package. Ping by using the Cisco console. There are 10000 800 character packets and no loss occurs. Kelai ping tool, with more than 186000 million character packages and more than 60 loss. (This is the result of the previous step, and it will be adjusted again later)

3. Shake motion. Cisco 7911 IP address, g.711u, average shaking activity 5 ms, maximum shaking Activity 15 ms, qualified.

(In the lower part, 1080 p red flag can be played through the Local Area Network. You can drag the video or stream)
